CCS/MSP430G2553: BREAKPOINT -> PWM STOPP

Friedrich Prof. Dr. Bloedow

Part Number: MSP430G2553
Other Parts Discussed in Thread: TMS320F28069

Tool/software: Code Composer Studio

Hello,

Launchpad MSP-EXP430G2 -> MSP430G2553.

PWM on P2.2 and P1.6.

When the program runs on a BREAKPIONT, the PWM stops.

Can one adjust that somewhere, that the PWM keeps running, as with the
Picolo (TMS320F28069 ... ) series?

Or at least that the PWM outputs when reaching a BREAKPOINT
to assume a predeterminable state?

Hello,

found it -> DEBUGGOPTIONEN.
Unfortunately, there is a line below me

"No module clock control available on this device".

Is already a serious limitation.

Which MSP430 is it working on?
Is there somewhere a MSP430 table that says where and with which DEBUGGER it works?

Hi,

Yes you can set CCS to keep the PWM running.

After you connect the MCU and enter the debug mode. The clock control settings could be changed under Tools -> debugger operations -> MSP43x debugger operations

For more information, you can refer to this app note:Advanced Debugging Using the Enhanced Emulation Module (EEM) With Code Composer Studio Version 6.pdf

Hi,
sorry, but CCSV6 is old. I have CCSV8, and there comes the message
"No module clock control available on this device".
Why does not this work with the CCSV8?
Once again, which MSP430 and CCSV8 can continue to run the PWM on a BREAKPOINT?
Is there a table that gives information about this possibility (MSP430XXXXX -> PWM continues with a BREAKPOINT)?
With kind regards Friedrich

Hi,

The steps I shown is operating on CCSV8. I tried this function on FR4133 and I could control the clock of Timer_A separately.

Today, I test the function on a G2553 board and find the same question just like you.

Since the EEM model can only stop MCLK, I think a work-around way is that: open the clock of ACLK, SMCLK or TACLK. Choose anyone of these clock sources as the Timer_A model clock. Then, PWM can work on debug mode.

You can find the answer in the app note on the bottom of page 40.5861.Code Composer Studio™ IDE v8.x for MSP430™ MCUs.pdf

Hi,
thanks for the answer.
To bypass the error in CCSV8 my work-around is
if (! FLY_BACK_COVERTER_PWM) // P2.2 TA1
{ // P2.2 is now 0 !!!!
UI_BREAK = 0; // !!! BREAKPOINT only here !!!!
}
So the output is also right in the SAVE position.
With kind regards Friedrich
